Serious Opinion on This

I think its kind off annoying when i try to find different stuff and get the same as last time. But put in perspective I don't think there's much the administrators can do to prevent it, unless its reported to them.
Take into consideration how long time it takes to confirm whether its duplicated, or not.
And then consider the man power it will take to keep the whole site clear at all times.
I highly doubt that its an easy project.
All that been said, i do agree that it would be nice if they could keep it off the site. But it's not that important to me in the end
